The dimensions of a rectangular pyramid are shown in the diagram.

Question

6 millimeters. 5 millimeters. 4 millimeters.



What is the volume of the rectangular pyramid in cubic millimeters?

15 mm3

120 mm3

60 mm3

40 mm3

Answer 1

To find the volume of a rectangular pyramid, you use the formula V = (1/3) * base area * height.

First, calculate the base area of the rectangular pyramid:
Base area = length * width
Base area = 6 mm * 5 mm
Base area = 30 mm2

Now, calculate the volume of the rectangular pyramid:
V = (1/3) * 30 mm2 * 4 mm
V = 40 mm3

Therefore, the volume of the rectangular pyramid is 40 mm3.
